Conkers is played with the seed of the horse chestnut tree, threaded onto a shoelace. One player holds their conker dangling; the other takes a deliberate swing and tries to smash it. They alternate until one conker breaks. It is autumn, it is a playground, and everyone in Britain has done it.
The rules
- Drill a hole through the conker, thread a shoelace through, knot the end.
- Players toss to decide who strikes first.
- The defender holds their conker still at arm’s length; the striker wraps the lace round their hand and swings.
- Three attempts per turn, then swap.
- If the strings tangle, the first to shout “strings!” gets an extra go.
- The game ends when one conker is destroyed.
The scoring
A fresh conker is a none-er. Beat one and it becomes a one-er, then a two-er, and so on. Crucially, a victorious conker inherits the score of the one it beat plus one — so defeating a sixer makes your one-er a seven-er in a single strike. This produces conkers with impressive and largely unverifiable reputations.
The cheating
An entire folk technology exists for hardening a conker, and every British child knows it:
- Baking in a low oven.
- Soaking in vinegar, the most commonly cited method.
- Painting with clear nail varnish.
- Keeping last year’s conker in a dark drawer for twelve months, which genuinely works and is generally considered legitimate.
All of these are cheating, all of them are universally practised, and accusations fly constantly.
The health and safety myth
You will hear that British schools banned conkers, or made children wear safety goggles. This is very largely untrue, and it became such a persistent story that the Health and Safety Executive published a page specifically debunking it, noting that a handful of schools had acted on their own — often over nut allergies or falling branches rather than the game — and that the HSE had never banned anything of the kind.
The story survives because it is a satisfying thing to be annoyed about, which is a very British reason for a myth to persist.
The World Conker Championships
Held every October in Northamptonshire since 1965, and entirely serious in its own way. Several hundred competitors take part, conkers and laces are supplied by the organisers to prevent tampering, and there are men’s, women’s and team titles. It raises money for charities supporting blind and partially sighted people.
The tree
The horse chestnut is not native — it arrived from the Balkans in the sixteenth century. It is now under real threat from leaf miner moth and from bleeding canker, and a great many British horse chestnuts look brown and ragged by August as a result.
Note also that horse chestnuts are not edible and are mildly poisonous. The sweet chestnuts sold roasted at Christmas markets come from an entirely different tree.
